To all 'whom 'it 'may concern:

Be it known that I, WILLIAM H. FAHR- Nnr, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvementl in Molding Apparatus for Constructing Sunken Concrete Structures, of which the following is a specification.

My invention relates to aparatus for use in the practice of the meth oi'constructin sunken concrete strncturesorming the su ject of my concurrent -ap lication -for Letters Patent of the United States, Serial No. L1-1,594, led on the third day of August, 1908. The method referred to involves, generally stated, the `.molding of sunken, and more es ecally submerged, concrete structures, suc as sea-walls, foundations, piers and the like, in successive sections and bonding the sections together by sinking a lined moldy into 'the bed of the body of water 4 structure, withdrawing the sand and water and replacin the-same with` concrete lled into the mol ,.thereupon vwithdrawing the mold-casing to be used for forming the next succeeding section of the structure but leavin the mold-lining embedded to sup? port t e concrete while it is setting, after which the sectional lining is removed to be used again in moldingadditional sections; and these operations 'are repeated until the structure is completed.

The work for which VI have more especially designed my improvement is that of constructing seawalls, so that the description hereinafter contained is confined to Its use in that connection.

In the acompan g drawings, Figure 1 is a perspectiveview of the mold-casing; Fig. 2 is a similarbroken view of a suctionpipe and nozzle or emptying the mold of s and and water but shown etached from the casing; Fig. 3 is perspective view showing the 4parts of the sectional mold-lini or sheeting and the gate' Vin their Aunassfem led relation; Fi 4 is a plan view showing the complete ino d in the condition in which it is used for forming the initialwall-section, Fig. 5 is a similar view, in the nature of a diagram, showing the condition of the aparatus in the progress of the work, and

ig. 6 is a broken longitudinal vertical' section, illustrating, by way of a diagram, the progress of fthe work. y

to be equipped with the I '3l (Fig. 6 the casin The mold consists of a casing 7 of suitable shape and dimensions, provided with an opening 8 extending t rou hout its length in one side, the openin eing between flanges 9 projecting tower each other crosssection and open at both ends, and is formed, by preference, of sheet-steel, being reinforced at intervals. by 'stren theningribs 10 and provided with a lexib e hanger 11 by which to suspend it from a crane, derrick or boom (not shown) for lowering it into lace and withdrawing it. At the top of tie casing is a bracket 12 for secur ing in osition a suction-pipe 13 leading from a suction-pump (not shown) and terminating i'n a hose 14 earryinga nozzle 15 on its free end. A gate 16 (iigs. 3, 4 and 5), used, as hereinafter explained, for closin the open side of the casing, is formed wit 1 sockets 17 alon its inner lateral edges, adjacent to each o which on the inner face of the gate extends lengthwise thereof a stop o r iiange 18; and on the outer face of the gate are bars 19 of Z-shape in cross-section .forming Guide-sockets 20 along its lateral ed s. Tie gate is also shown to be provi' on its outer face or back with strengthening-ribs 21 and it contains a hole 22 near its upper end at which to engage it for lowerlng and raising it throu h the medium of .a crane, or the like. Simi ar side-sheets 23 for lining the casin and of which a larve number is provide for use in pairs in mo ding a wall-section, contain recesses or notches 24 and holes 25 at one end, and each'side-sheet is rovided alongl one outer edge with an ang e-iron 26, an along its oposite edge with bars 2,7 terminating in soc et heads 28; and a back-sheet 29 vformsection is e ui ped on its 30 by w ic 4to handle the aforesaid ing another linin upper end with a oo) it through the me ium of crane, or the like.

To use my improved apparatus for constructing a concrete Wall in a body of water is placed on end in the selecte position, t e gate 16 is adjusted with itssockets 20 enga 'ng the iianges 9 to close the opening 8, an the suction-pipe is caused to withdraw sand and water out of the casing and thereby sink it to the desired depth in the bed 32,of,j;he body of water. The side-shects 23 are thereupon introduced i at rightangles tol the casing-sides. The

casing, as shown in Fig. 1., is of rectangular lll) lty

into the empty easing, being guided by niovthe rear ends of the side-sheets abut ae'ainst the bachV ot' the easin,r and are braved in its .i

eornerportions by the soeltetheads 2i' tit ting the saine. l`he side-sheets are braved in position by a eross-rod its threaded ends willi stops, shown. as eollars il to hear against the inner sides` otl the sheets when 'said ends are introduced into the notches 2t, when nuts ijf are applied to them to elanip the sheets. rlhe haeltY- .sheet 2D is then intrti'dneed into the casing between the side-sheets, beingi sustained by sinking it`r like the other portions of the structure` into the sand-bed 32 and by bear ing at its upper end against the rod $53. To then forni the first section of 'the sea-wall to be eonstrneted, the niold is filled= in the .space between the parts lt, 225 and ttl, with Concrete, whereupon the easing' is raired hy the hanger l1 away frein the sheeting.J ineluding' the gate, thus leaving the saine provided. near a support i'or the section while the (concrete l setting. Meantime the easing is lowered into position adjaeent to the firstanolded A t veines .set so that;` it will stand without sop ing the :inglobato 2U in the sockets l?, and ti port l'roi'n the sheeting7 the latter is wi dra wn to be used with the rfasiiigj in forniing a tresh seetion; and, it will be under- -'tood. when the lining ol.l the first-molded seetion is thus' renioi'ed7 the gate used to et operate with it also removed, the with dra wal beingr elteeted by applying the den rielny or the like, to the sheets, after first re-Y moving' the rod l.
